A comparative study to investigate two configurations of a two-stage evaporator in a CO2 heat pump chiller
(Chapter; Peer reviewed, 2023)This study is carried out to investigate the performance of a CO2 heat pump chiller that provides heating and cooling simultaneously. For heating applications, hot water is produced at 90°C; while for cooling applications, ... -
Comparing Three Methods for Design Analyses of Rankine Cycle for Waste Heat Recovery from Natural Gas Compression
(Science et technique du froid;2020-1, Chapter; Peer reviewed, 2020)This study applies three methods for design of Rankine cycles utilizing waste heat in the oil and gas industry. The methods differ in the level of detail of heat exchanger model applied and in the flexibility with respect ... -
Comparison between synthetic ester and mineral oil impregnated transformer paper aging markers
(Proceedings of IEEE International Conference on Dielectric Liquids;, Chapter; Peer reviewed, 2017)For transformers in service, aging markers from cellulose in oil such as furans, water, methanol and acids are measured for diagnostic purposes. The content of these indicators, measured in oil, may therefore vary with ... -
A Comparison of Consistent Discretizations for Elliptic Problems on Polyhedral Grids
(Chapter, 2020)In this work, we review a set of consistent discretizations for second-order elliptic equations, and compare and contrast them with respect to accuracy, monotonicity, and factors affecting their computational cost (degrees ... -
Comparison of Offline VLF PD Measurements and Online PD Measurements on a 50-Year-Old Hydrogenerator Stator in Norway
(Chapter; Peer reviewed, 2018)Stator winding insulation is the part of the hydrogenerator experiencing the highest number and the most damaging failures. Partial discharge (PD) measurement, both offline and online, are commonly used for condition ... -
COMPARISON OF PARTICLE-RESOLVED DIRECT NUMERICAL SIMULATION AND 1D MODELLING OF CATALYTIC REACTIONS IN A PACKED BED
